Interpretation
Alexi (M-DR) started at 8:40 AM; Ian (Z-DR) started at 8:51 AM. That gave Alexi a 11 minutes head start on Ian. On foot, Alexi ran 2:20:21 and Ian ran 2:10:01 — Ian was 10:20 faster than Alexi. Alexi took official place 1361st (time-based 1353rd) and Ian took official place 1364th (time-based 1331st).
